Title: Improvements in or relating to automatic telephone exchange systems
IPC: H04M15/08
Filed: 1941-02-14
Abstract: 549,848. Automatic exchange systems. STANDARD TELEPHONES & CABLES, Ltd., LOWRY, L. P., and PETERS, G. E. Feb. 14, 1941, No. 2028. [Class 40 (iv)] In a system in which a variable number of digits are transmitted by means of impulses, the last impulse train is distinguished by a lengthening of the final impulse or by the addition of a long impulse. The invention is applied to an arrangement for identifying calling lines of the kind described in Specification 529,718, in which the number of impulses in each train is determined by a hunting movement. The tens digit is sent during the vertical movement of a switch LA, with a switch CA stepping in synchronism, and the units digit is sent during the rotary movement of LA. Relay F responds when a distinctive tone is found and terminates the impulse train. Relay PC pulls up after the tens digit and prepares a circuit for relay FP. As shown in Fig. 4, this relay energizes during the last impulse of the units train and maintains the impulse until sluggish relay PA falls back. In another arrangement, Fig. 1 (not shown), relay FP energizes over impulse springs MIS after relay IG has fallen back and gives an additional long impulse. A.C. make impulses are sent over the circuit J as shown; but D.C. break impulses may also be employed, the impulsing contacts then being in series. The impulses are used to control a number indicator, and the long final impulse serves to release a sluggish relay which completes the setting operations and lights the display lamps of a lamp indicator or illuminates the numberwheels of an indicator of the kind described in Specification 542,146, [Group XXXVIII].
